SlIELFORD, HLATTOni-lA. 25 



This low country speciinen may, possibly be a distinct species, but in colour 

 and general appearance it ' reseinbles so closely tlie mountain forms that I hesitate 

 to separate it, at any rate iintil a male froni tlre same habitat is found. 



Ceratiiiopterca perimlclira sp. n. 



(PI. 2, Hg. 2; l'l. 3, lig. l;i.) 



o". Minute, rufo-testaceous, nitid. Head castaneous, rufoiis on Vertex, basal 

 joints of antennae testaceous, reniaiuder fuscous; Vertex covered by pronotiim. Pro- 

 notuni trapezoidal with two longitudinal vittae castaneous. Tegmina coriaceous, just 

 failing to reach end of abdomen, a broad humeral stripe which extends as two narrow 

 lines along the radial and ulnar veins, castaneous; 12 costal veins, anterior ulnar bi- 

 ramose, the reniaining veins not visible. Wings rudimentary. Abdomen above rufo- 

 testaceous with lateral margins and a central patch castaneous; scent-glands oi^ening 

 on 7'^ tergite, at base of two deep depressions ; supra-anal lamina produced, rounded; 

 cerci short, rufo-testaceous; abdomen beneath castaneous, sub-genital lamina rufo- 

 testaceous, rounded, produced, styles asymmetrically placed. Legs testaceous, front 

 femora as in preceding species. 



?. Somewhat larger, dark castaneous, the diso of the pronotum and field of 

 tegmina rufous, lateral margins of pronotum and mediastinal field of tegmina pale 

 testaceous; abdomen entirely castaneous, cerci fuscous. Tegmina shorter, wings rudi- 

 mentary, supra-anal lamina triangulär, sub-genital lamina ample, semi-orbicular. 

 Legs testaceous, except the bases of the coxae which are castaneous. 



c?. Length of body 5,6 mm.; length of tegmina 4 mm. 

 ?. » » !) 7 mm.; » » » 3,8 mm. 



Kilimandjaro: Kibonoto 1,000 — 1,900 metres (March to May, Sept., Oct.), 

 5 c?c?, 5 ¥?, 1 larva. 



This is quite the smallest species of the genus; in colouration it approaches 

 C. ilimidiata Gerst. but it lacks the transverse band on the tegmina. 



Ceratiuoptera ovata sp. n. 



2. Convex, castaneous, nitid. Vertex of head not covered by pronotum, 

 antennae piceous. Pronotum trapezoidal, sides deflexed, posterior margin obtusely 

 angled, lateral margins paler than the disc. Tegmina reaching base of supra-anal 

 lamina, mediastinal area testaceous, 14 costals, anal vein impressed, remaining veins 

 obscure, the part of the right tegmen overlapped by the left reticulated. Wings 

 shorter than tegmina, 8 costals, their apices slightly incrassated, the last and apex 

 of radial vein tri-ramose, ulnar vein bifurcated. Abdomen and cerci piceous, supra- 

 anal lamina triangulär, sub-genital lamina ample, semi-orbicular. Legs riifous. 



Length of body 9 mm.; length of tegmina 6,4 mm.; pronotum 3 mm. x 3,o mm. 



Usambara, I ?. 



C. dimidiata Gerst. is probablj' the nearest ally of the species but it was des- 

 cribed from au imperfect specimen so that certainty on this point is impossible.
